本发明涉及一种传感器、双模式触控模组及双模式触控电子装置。The invention relates to a sensor, a dual-mode touch module and a dual-mode touch electronic device.
背景技术Background technique
目前，触控产品主要包括手指触控产品和笔写触控产品，该等触控产品的触控模式基本上是电容式触控模式和电阻式触控模式。At present, touch products mainly include finger touch products and pen touch products, and the touch modes of these touch products are basically capacitive touch mode and resistive touch mode.
其中，电阻式触控主要是通过在显示屏的触控区域设置上下两层不接触的ITO导电薄膜，以实现对触控点的感测。其缺点主要是：上下两层ITO导电薄膜容易出现接触故障，进而使得电阻式触控的反应不灵敏，对手写或笔写的解析度较低。Among them, the resistive touch control mainly realizes the sensing of the touch point by arranging upper and lower layers of non-contact ITO conductive films in the touch area of the display screen. The main disadvantages are: the upper and lower layers of ITO conductive film are prone to contact failure, which makes the response of resistive touch insensitive, and the resolution of handwriting or pen writing is low.
相对于电阻式触控模式，电容式触控模式的触控产品的灵敏度有一定的提高。然而，电容式触控模式即电容耦合触控模式需要设置较密集排布的阵列结构，该阵列结构需要设置能够输出或输入电流信号的阵列，由此导致控制电路或芯片的I/O接口增加，使得触控产品的反应速度降低，进而导致无法较好地识别触控点的位置信息。Compared with the resistive touch mode, the sensitivity of touch products in the capacitive touch mode has been improved to a certain extent. However, the capacitive touch mode, that is, the capacitively coupled touch mode, requires a densely arranged array structure, which requires an array capable of outputting or inputting current signals, thereby increasing the I/O interface of the control circuit or chip. , so that the reaction speed of the touch product is reduced, which leads to the inability to better recognize the position information of the touch point.
现有技术中还出现一种采用电磁感应触控模式的触控产品，该电磁感应触控模式采用感应电磁信号的方式获取电磁笔在电磁感应天线阵列的位置信息，以实现电磁笔触控点的定位。然而该类触控产品只能采用电磁笔书写，无法识别手写模式中触控点的识别，其适用范围比较受限。In the prior art, there is also a touch product that adopts the electromagnetic induction touch mode. The electromagnetic induction touch mode adopts the method of inducting electromagnetic signals to obtain the position information of the electromagnetic pen in the electromagnetic induction antenna array, so as to realize the position information of the electromagnetic pen touch point. position. However, this type of touch products can only be written with an electromagnetic pen, and cannot recognize the touch points in the handwriting mode, and its scope of application is relatively limited.
为此，大多触控产品生产商将电容式触控模式和电磁感应触控模式叠加在一起以实现手写和笔写结合的触控模式；该电容式触控模式的触控区域需要设置在电磁式触控模式的触控区域之上；也就是说：需要在同一个需要触控的设备上设置两套相互独立的阵列结构，并使之相互叠加，以便能够实现两种模式的位置信息的识别。然而，每一阵列结构需要连接各自的处理电路，使得整个触控产品的结构复杂，体积庞大、制造成本高。并且在触控产品的使用过程中，还会出现电容式触控模式和电磁感应触控模式的相互干扰。因此，上述任一触控产品均无法较好地满足使用者的需求。For this reason, most touch product manufacturers superimpose the capacitive touch mode and the electromagnetic induction touch mode to realize the touch mode combining handwriting and pen writing; the touch area of the capacitive touch mode needs to be set in the electromagnetic In other words, it is necessary to set up two sets of independent array structures on the same device that needs to be touched, and make them superimposed on each other, so as to realize the location information of the two modes. identify. However, each array structure needs to be connected with its own processing circuit, which makes the structure of the entire touch control product complex, bulky and high in manufacturing cost. Moreover, during the use of touch products, there will be mutual interference between the capacitive touch mode and the electromagnetic induction touch mode. Therefore, none of the above-mentioned touch products can better meet the needs of users.

Wherein the first-direction conductors in the first-direction conductor group are distributed in a combination arrangement in a mathematical formula, the combination formula is Cmn , n and m are natural numbers greater than or equal to 4, and m<=n, for example , n can be 5, 6, 8, 7, 9, 10, 19 or 32 and so on. That is to say, the combination of the first conducting wire and the second conducting wire at any position of the first direction conducting wire group of the first direction conducting wire and the adjacent previous or subsequent conducting wire is not repeated with the combination of the adjacent two conducting wires at any other position .

如图1A、1B所示，第一方向导线201a的开口部具有连接外部控制部件100的第一连接端204和第二连接端205。在本实施例中，第二连接端205串接有模式切换电子开关202，该第二连接端205经模式切换电子开关202能够被连接到外部控制部件100。第一方向导线的U形的两个边上(即第一导线和第二导线)电性连接有多个第一电容耦合触控部件203，或者第一方向导线的U形的任一边上(第一导线或者第二导线)电性连接有多个第一电容耦合触控部件203。该第一电容耦合触控部件203的数量、大小、形状依据实际电路结构的需求设定。通常，第一电容耦合触控部件203的数量与第一方向导线组和第二方向导线组的交叉点数量相同。当然，如图1C所示，图1C中示出的第二方向导线组的结构类同于第一方向导线组的结构。As shown in FIGS. 1A and 1B , the opening of the first direction wire 201 a has a first connection end 204 and a second connection end 205 connected to the external control component 100 . In this embodiment, the second connection end 205 is connected in series with the mode switch electronic switch 202 , and the second connection end 205 can be connected to the external control unit 100 through the mode switch electronic switch 202 . A plurality of first capacitive coupling touch components 203 are electrically connected to the two sides of the U-shape of the wire in the first direction (ie, the first wire and the second wire), or any side of the U-shape of the wire in the first direction ( The first wire or the second wire) is electrically connected to a plurality of first capacitively coupled touch components 203 . The quantity, size and shape of the first capacitive coupling touch component 203 are set according to the requirements of the actual circuit structure. Usually, the number of the first capacitively coupled touch control components 203 is the same as the number of crossing points of the first direction wire group and the second direction wire group. Of course, as shown in FIG. 1C , the structure of the second-direction wire group shown in FIG. 1C is similar to the structure of the first-direction wire group.
在图1C中第二方向导线101a的开口部具有连接外部控制部件100的第一连接端104和第二连接端105。在本实施例中，第二连接端105串接有模式切换电子开关102，该第二连接端105经模式切换电子开关102能够被连接到外部控制部件100。第二方向导线的U形的两个边上(即第一导线和第二导线)电性连接有多个第二电容耦合触控部件103，或者第二方向导线的U形的任一边上(第一导线或者第二导线)电性连接有多个第二电容耦合触控部件103。该第二电容耦合触控部件103的数量、大小、形状依据实际的电路结构的需求设定。当然，第二电容耦合触控部件103的数量与第一方向导线组和第二方向导线组的交叉点数量相同。可以理解的是第二电容耦合触控部件103与第一电容耦合触控部件203的数量相同，且传感器中的第一电容耦合触控部件和第二电容耦合触控部件在第一方向导线和第二方向导线相互交叉的区域交错叠设。In FIG. 1C , the opening of the second direction wire 101 a has a first connection end 104 and a second connection end 105 connected to the external control component 100 . In this embodiment, the second connection end 105 is connected in series with the mode switch electronic switch 102 , and the second connection end 105 can be connected to the external control unit 100 through the mode switch electronic switch 102 . A plurality of second capacitive coupling touch components 103 are electrically connected to the two sides of the U-shape of the wire in the second direction (that is, the first wire and the second wire), or any side of the U-shape of the wire in the second direction ( The first wire or the second wire) is electrically connected to a plurality of second capacitively coupled touch components 103 . The quantity, size and shape of the second capacitively coupled touch components 103 are set according to the requirements of the actual circuit structure. Of course, the number of the second capacitively coupled touch components 103 is the same as the number of intersections of the first direction wire group and the second direction wire group. It can be understood that the number of the second capacitively coupled touch components 103 is the same as that of the first capacitively coupled touch components 203, and the first capacitively coupled touch components and the second capacitively coupled touch components in the sensor are wired in the first direction and The areas where the conducting wires in the second direction intersect with each other are interlaced and overlapped.
当第一方向导线的模式切换电子开关202闭合时，该第一方向导线工作于电磁感应触控模式，用以感应电磁笔发出的电磁信号。当第一方向导线组的所有模式切换电子开关202均闭合时，电磁笔在第一方向导线组的竖向上下移动时，可以通过外部控制部件测量任一第一方向导线输出的交变信号，比较获取输出最大的交变信号在第一方向导线组所分布的导线位置即可直接获知并确定电磁笔竖向(即Y轴向)的准确位置。相应地，当第二方向导线的模式切换电子开关102闭合时，该第二方向导线工作于电磁感应触控模式，用以感应电磁笔发出的电磁信号。当第二方向导线组的所有模式切换电子开关102均闭合时，电磁笔在第二方向导线组的横向水平移动时，可以通过外部控制部件测量任一第二方向导线输出的交变信号，比较获取输出最大的交变信号在第二方向导线组所分布的导线位置即可直接获知并确定电磁笔横向(即X轴向)的准确位置。When the mode switching electronic switch 202 of the wire in the first direction is closed, the wire in the first direction works in the electromagnetic induction touch mode to sense the electromagnetic signal sent by the electromagnetic pen. When all mode switching electronic switches 202 of the first direction wire group are closed, when the electromagnetic pen moves vertically up and down in the first direction wire group, the alternating signal output by any first direction wire can be measured by the external control component, By comparing and obtaining the position of the wires distributed by the wire group in the first direction where the alternating signal with the maximum output is obtained, the accurate vertical (ie, Y-axis) position of the electromagnetic pen can be directly known and determined. Correspondingly, when the mode switching electronic switch 102 of the wire in the second direction is closed, the wire in the second direction works in the electromagnetic induction touch mode for inducing the electromagnetic signal sent by the electromagnetic pen. When all the mode switching electronic switches 102 of the second direction wire group were closed, when the electromagnetic pen moved horizontally in the direction of the second direction wire group, the alternating signal output by any second direction wire could be measured by the external control part, and compared The exact position of the electromagnetic pen in the transverse direction (namely the X-axis) can be directly known and determined by obtaining the positions of the wires distributed by the wire group in the second direction with the maximum output alternating signal.
由于第一方向导线组和第二方向导线组相互交叉放置(如图1A的虚线框中所示结构)，因此能够经由两个方向导线传递的电磁感应信号检测出电磁笔位于天线阵列的具体位置。Since the first direction wire group and the second direction wire group are placed across each other (the structure shown in the dashed box in Figure 1A), the electromagnetic induction signal transmitted by the two direction wires can detect the specific position of the electromagnetic pen in the antenna array .
需要进一步说明的是，上述第一方向导线组和第二方向导线组相互交叉，同时构成电容耦合触控天线阵列；且第一方向导线组和第二方向导线组之间相互绝缘的。在图1A所示的传感器中，将所有的模式切换电子开关(102和202)断开，此时，第一方向导线和第二方向导线均工作于电容耦合触控模式。第一方向导线和第二方向导线中各自的第一连接端与外部连接控制部件电导通。外部控制部件接收到电容耦合信号后，经处理可获知手指的触控位置。应了解的是，在实际设置有本实施例传感器的电路结构中，可将传感器中的模式切换电子开关102和202设于外部控制部件100区域，以便于整个电路结构的集成控制。It should be further explained that the first direction wire group and the second direction wire group intersect each other to form a capacitively coupled touch antenna array; and the first direction wire group and the second direction wire group are insulated from each other. In the sensor shown in FIG. 1A , all mode switching electronic switches ( 102 and 202 ) are turned off, and at this time, both the first direction wire and the second direction wire work in the capacitive coupling touch mode. The respective first connection ends of the first direction wire and the second direction wire are in electrical conduction with the external connection control component. After receiving the capacitive coupling signal, the external control part can know the touch position of the finger after processing. It should be understood that, in the actual circuit structure provided with the sensor of this embodiment, the mode switching electronic switches 102 and 202 in the sensor can be set in the area of the external control part 100, so as to facilitate the integrated control of the entire circuit structure.
上述实施例中的传感器通过模式切换电子开关将传感器中的天线阵列切换为电容耦合触控模式或者电磁感应触控模式，能够有效克服现有技术中同时具有电容、电感触控双模式产品中，电容耦合触控模式和电磁感应触控模式相互干扰的问题。特别地，上述实施例中采用数学中组合排列方式排布的U形的第一方向导线组和第二方向导线组相互交叉，使得每一相邻的第一方向导线或第二方向导线的组合是唯一的，进而最后形成的天线阵列的交叉点的位置是唯一的。The sensor in the above embodiment switches the antenna array in the sensor to the capacitive coupling touch mode or the electromagnetic induction touch mode through the mode switching electronic switch, which can effectively overcome the problems in the prior art with both capacitive and inductive touch modes. The problem of mutual interference between the capacitive coupling touch mode and the electromagnetic induction touch mode. In particular, in the above-mentioned embodiment, the U-shaped first-direction wire group and the second-direction wire group arranged in a combination arrangement in mathematics intersect each other, so that each combination of adjacent first-direction wires or second-direction wires is unique, and then the position of the intersection point of the finally formed antenna array is unique.
相对比现有电容耦合触控技术，上述实施例中，通过设置在U形第一方向导线和第二方向导线的第一导线和第二导线上的第一电容耦合触控部件103和第二电容耦合触控部件203与相邻电容耦合部件的组合排列，使相同第一导线数或第二导线数扩展了更大的触控区域，能够有效减少传感器与外部控制部件之间的I/O接口，进而使得外围电路结构大幅简化、便于集成，使处理信号数据量减少、处理速度大幅度提高。I/O接口和要处理的数据量减少能够使得包含该传感器的触控产品的处理速度提高，且使得包含本发明传感器的触控产品如手机、平板电脑等的结构简单，制造成本低，并能有效地满足使用者兼用电磁笔和手指触摸等两种触控输入的需求。Compared with the existing capacitive coupling touch technology, in the above embodiment, the first capacitive coupling touch component 103 and the second The combined arrangement of the capacitive coupling touch component 203 and adjacent capacitive coupling components expands a larger touch area with the same first or second number of wires, which can effectively reduce the I/O between the sensor and the external control component interface, which greatly simplifies the peripheral circuit structure, facilitates integration, reduces the amount of signal data to be processed, and greatly improves the processing speed. The reduction of the I/O interface and the amount of data to be processed can increase the processing speed of the touch products including the sensor, and make the touch products including the sensor of the present invention, such as mobile phones and tablet computers, simple in structure, low in manufacturing cost, and It can effectively meet the user's demand for two kinds of touch input such as electromagnetic pen and finger touch.
以下通过图2A至图2C详细说明本发明的传感器实施例中的天线阵列识别电磁信号的原理；其中，图2A为第一方向导线内识别电磁信号的强度变化的示意图，图2B为第一方向导线组内识别电磁信号的强度变化的示意图，图2C为天线阵列识别电磁信号的示意图。The principle of identifying electromagnetic signals by the antenna array in the sensor embodiment of the present invention will be described in detail below through FIGS. 2A to 2C; wherein, FIG. 2A is a schematic diagram of identifying the intensity change of electromagnetic signals in the wire in the first direction, and FIG. 2B is in the first direction. A schematic diagram of identifying the intensity variation of the electromagnetic signal within the wire group, and FIG. 2C is a schematic diagram of identifying the electromagnetic signal by the antenna array.
图2A中线圈5通有交变电流，线圈5周围会产生交变磁场，交变磁场的磁力线穿过第一方向导线201a，第一方向导线201a则能够感应电磁信号并输出交变感应电压。当线圈5在第一方向导线201a的上下移动时，第一方向导线201a输出的交变感应电压是不同的，如图2A中，线圈5分别位于第一方向导线的位置14、中心位置13和位置15时，通过测量得知线圈5位于第一方向导线201a的竖向中心时，第一方向导线201a输出的交变感应电压是最大的。当然，基于电磁场原理可知，在同一高度，在导线201a内，水平移动线圈5时，第一方向导线201a输出的交变感应电压是不发生变化的。In FIG. 2A , the coil 5 is supplied with an alternating current, and an alternating magnetic field is generated around the coil 5 . The magnetic field lines of the alternating magnetic field pass through the first direction wire 201a, and the first direction wire 201a can induce electromagnetic signals and output an alternating induced voltage. When the coil 5 moves up and down on the first direction wire 201a, the alternating induced voltage output by the first direction wire 201a is different, as shown in Figure 2A, the coil 5 is located at the position 14, the center position 13 and the first direction wire respectively. When the position is 15, the measurement shows that when the coil 5 is located at the vertical center of the first direction wire 201a, the alternating induced voltage output by the first direction wire 201a is the largest. Of course, based on the principle of electromagnetic field, it can be known that at the same height, when the coil 5 is moved horizontally within the wire 201a, the alternating induced voltage output by the wire 201a in the first direction does not change.
另外，如图2B所示，第一方向导线组中的第一方向导线201a以相等间距组合排列，试验验证线圈5位于第一方向导线201a的竖向中心时，第一方向导线201a输出的交变感应电压U3最大；以及线圈5上移至偏向于第一方向导线201b的竖向中心时，第一方向导线201b输出的交变感应电压U2最大；进一步地，线圈5再上移至第一方向导线201c的竖向中心时，第一方向导线201c输出的交变感应电压U1最大。由上可在第一方向导线组中获取线圈5在竖向上的位置信息。也就是说，平行设置多个间距相等的第一方向导线，且使该多个平行设置的第一方向导线以组合排列的方式分布，进而在外部控制部件中通过比较该些第一方向导线输出的交变感应电压的大小，即可获取线圈5在竖向上的准确位置。故，上述实施例中传感器的天线阵列采用如图2B中排列的第一方向导线以便较好地识别线圈5在竖向(Y轴向)准确的位置信息。In addition, as shown in FIG. 2B , the first direction wires 201a in the first direction wire group are arranged at equal intervals, and the test verifies that when the coil 5 is located at the vertical center of the first direction wires 201a, the alternating current output by the first direction wires 201a The variable induced voltage U3 is the largest; and when the coil 5 moves up to the vertical center biased to the first direction wire 201b, the alternating induced voltage U2 output by the first direction wire 201b is the largest; further, the coil 5 moves up to When the vertical center of the wire 201c in the first direction is at the vertical center, the alternating induced voltageU1 output by the wire 201c in the first direction is the largest. From the above, the vertical position information of the coil 5 can be obtained in the first direction wire group. That is to say, a plurality of first-direction wires with equal intervals are arranged in parallel, and the plurality of first-direction wires arranged in parallel are distributed in a combined arrangement, and then the output of the first-direction wires in the external control unit The exact position of the coil 5 in the vertical direction can be obtained by the magnitude of the alternating induced voltage. Therefore, the antenna array of the sensor in the above embodiment adopts the wires arranged in the first direction as shown in FIG. 2B so as to better identify the accurate position information of the coil 5 in the vertical direction (Y axis).
同样原理，在图2C中，线圈5位于第二方向导线101a内的不同的水平位置，其第二方向导线101a输出的交变感应电压是不同的，以便获取线圈5在水平方向(X轴向)上的位置信息。In the same principle, in Fig. 2C, the coil 5 is positioned at different horizontal positions in the second direction wire 101a, and the alternating induced voltages output by the second direction wire 101a are different, so as to obtain the coil 5 in the horizontal direction (X axis ) on the location information.
参照图2C所示，天线阵列包括垂直交叉排列的第一方向导线组和第二方向导线组。当线圈5在天线阵列的任一位置时，通过获取并比较天线阵列中第一方向导线和第二方向导线输出的交变感应电压，可确定线圈5在天线阵列中的具体位置。Referring to FIG. 2C , the antenna array includes a first direction wire group and a second direction wire group arranged vertically and crosswise. When the coil 5 is at any position of the antenna array, the specific position of the coil 5 in the antenna array can be determined by obtaining and comparing the alternating induced voltages output by the wires in the first direction and the wires in the second direction in the antenna array.
参考图3A至图3H所示，图3A至图3H为本发明的传感器实施例中的电容耦合触控模式的原理分析示意图；其中，导体21可相当于触控的手指，导体23和导体24在相同层面并彼此独立绝缘。当导体21通过绝缘介质22贴合于彼此绝缘的导体23和导体24上时，导体21的左侧与导体23的贴合区等效为电容C1，导体21的右侧与导体24的贴合区等效为电容C2，由于导体21是一体结构，进而等效的电容C1和电容C2为串联连接，如图3C所示的等效电路。从3C所示的等效电路可知导体23与导体24间可相互传递交变电压。图3C示出了本发明中手指触控天线阵列中的交叉点的等效电路图，因手指与导体23和导体24间对一定频率的交流电压的交流阻抗(包括感抗、阻抗和/或容抗等)很大，相当于绝缘，而手指的直流阻抗较低，故手的触摸面等效为导体21，第一方向导线201a相当于导体23，第二方向导线101a相当于导体24。Referring to FIG. 3A to FIG. 3H, FIG. 3A to FIG. 3H are schematic diagrams of the principle analysis of the capacitive coupling touch mode in the sensor embodiment of the present invention; wherein, the conductor 21 can be equivalent to a touch finger, and the conductor 23 and the conductor 24 on the same level and independently insulated from each other. When the conductor 21 is attached to the conductor 23 and the conductor 24 which are insulated from each other through the insulating medium 22, the bonding area between the left side of the conductor 21 and the conductor 23 is equivalent to capacitance C1 , and the bonding area between the right side of the conductor 21 and the conductor 24 The combined area is equivalent to a capacitor C2 . Since the conductor 21 is an integral structure, the equivalent capacitor C1 and capacitor C2 are connected in series, as shown in the equivalent circuit in FIG. 3C . From the equivalent circuit shown in 3C, it can be seen that the conductor 23 and the conductor 24 can transmit alternating voltage to each other. 3C shows the equivalent circuit diagram of the cross point in the finger touch antenna array in the present invention, because the AC impedance (including inductive reactance, impedance and/or capacitance) between the finger and the conductor 23 and the conductor 24 to the AC voltage of a certain frequency resistance, etc.) is very large, which is equivalent to insulation, and the DC impedance of the finger is low, so the touch surface of the hand is equivalent to the conductor 21, the first direction wire 201a is equivalent to the conductor 23, and the second direction wire 101a is equivalent to the conductor 24.
如图3D所示(为后续方便说明，图3D中仅示意了一个第一方向导线和一个第二方向导线垂直交叉的示意图)，当第二方向导线的101a的第一连接端104通入交变信号8时，手指与交叉点1(图3D中的阴影部分)接触，以使交流信号8的回路被导通(也就是说，图3D中的触控点1之间的电容C7和C8导通)，由此可获取到第一方向导线201a的第一连接端204输出的交变信号9。当手指触控图3D中所示的交叉点2、3或4时，相对应的接触点2的C1和C2、接触点3的C3和C4、或接触点4的C6和C5被导通，进而可以检测到上述的交变信号9。由上所述，外部控制部件可以识别天线阵列中的电容耦合触控信号。As shown in Figure 3D (for the convenience of subsequent description, only a schematic diagram of a first-direction wire and a second-direction wire perpendicularly intersecting is shown in Figure 3D), when the first connection end 104 of the second-direction wire 101a passes into the AC When the signal 8 is changed, the finger is in contact with the cross point 1 (the shaded part in FIG. 3D ), so that the loop of the AC signal 8 is turned on (that is, the capacitor C7 and the capacitor between the touch point 1 in FIG. 3D C8 is turned on), so that the alternating signal 9 output by the first connection end 204 of the first direction wire 201a can be obtained. When a finger touches the intersection point 2, 3 or 4 shown in Fig. 3D, C1 and C2 of the corresponding contact point 2, C3 and C4 of the contact point 3, or C6 and C 4 of the contact point 4 C5 is turned on, and then the above-mentioned alternating signal 9 can be detected. From the above, the external control component can identify the capacitively coupled touch signal in the antenna array.
由于每一第一方向导线和第二方向导线均有四个交点，其输出交变信号9的位置也是相同的，上述图3D中示出的可能无法较好地判断手指位于交叉点(即触控点)1、2、3或4的具体位置，故以下结合3E至图3H详细说明外部控制部件获取电容耦合模式下的唯一位置信息。Since each first-direction wire and second-direction wire has four intersection points, the position of the output alternating signal 9 is also the same, it may not be possible to better judge whether the finger is located at the intersection point (i.e. touch point) shown in FIG. control point) 1, 2, 3 or 4, so the following describes in detail the unique position information acquired by the external control component in the capacitive coupling mode in combination with 3E to FIG. 3H.
参照图3E至图3H所示，图3E中导体21和导体23、导体21和24的贴合面相等，即C1和C2相等，图3F和图3G中导体21与导体23、导体24的贴合面不相等，进而C1在图3F和图3G中较大，由于导体21与导体23和24的贴合总面积一定，且C1和C2串联，故依据串联电容C＝C1*C2/(C1+C2)可知，只有C1和C2相等时，输出的交变信号是最强的，如图3H所示的各实验数据，其S1＞S2＞S3。当用手指取代导体21时，其产生的结果和上述模拟实验的结果是一致的。Referring to Fig. 3E to Fig. 3H, the bonding surfaces of conductor 21 and conductor 23, conductor 21 and 24 in Fig. 3E are equal, that is, C1 and C2 are equal, conductor 21 and conductor 23, conductor 24 in Fig. The bonding surfaces are not equal, andC1 is larger in Figure 3F and Figure 3G. Since the total bonding area of conductor 21 and conductors 23 and 24 is constant, andC1 andC2 are connected in series, according to the series capacitance C=C1 *C2 /(C1 +C2 ), it can be seen that only when C1 and C2 are equal, the output alternating signal is the strongest, and the experimental data shown in Fig. 3H is S1>S2>S3. When the conductor 21 is replaced with a finger, it produces results that are consistent with the above simulation results.
故，由于实际的传感器至少包括3根以上U形第一方向导线和第二方向导线，故具体结构中，各交叉点分别由第一电容耦合触控部件203和第二电容耦合触控部件103交错叠设，且天线阵列中的各交叉点均匀分布(如下的图7C所示)，进而可保证手指触控的交叉点至少为两个或两个以上，以便使外部控制部件通过获取和比较相邻的各个方向导线的第一连接端输出的最大的交变信号的位置，以获知触控点的准确位置信息(也就是说，借助于相邻交叉点输出的交变信号在各个方向导线的第一连接端输出的分布，可以准确区分图3D中的触控点1、2、3和4)，由此，通过触控点包含的至少相邻的两个交叉点能够唯一确定电容耦合触控模式下触控点的位置信息。Therefore, since the actual sensor includes at least three U-shaped wires in the first direction and wires in the second direction, in the specific structure, each cross point is controlled by the first capacitively coupled touch component 203 and the second capacitively coupled touch component 103 respectively. Staggered and stacked, and the cross points in the antenna array are evenly distributed (as shown in Figure 7C below), which can ensure that there are at least two or more cross points touched by fingers, so that the external control components can obtain and compare The position of the largest alternating signal output by the first connecting end of the adjacent wires in each direction, so as to know the accurate position information of the touch point (that is, the alternating signal output by the adjacent intersection points in each direction of the wire The distribution of the output of the first connection end of , can accurately distinguish the touch point 1, 2, 3 and 4 in Figure 3D), thus, the capacitive coupling can be uniquely determined by at least two adjacent intersections contained in the touch point The position information of the touch point in the touch mode.
需要说明的是，人体和手的大部位与天线阵列的交叉点之间的距离相对于手指与交叉点之间的距离要大很多，进而人体和手的大部位与天线阵列的交叉点产生的感抗、容抗、阻抗都是非常大的，故相对于手指在交叉点产生的容抗来说，身体其他部位可等效绝缘。It should be noted that the distance between the large part of the human body and the hand and the intersection point of the antenna array is much larger than the distance between the finger and the intersection point, and thus the large part of the human body and hand and the intersection point of the antenna array Inductive reactance, capacitive reactance, and impedance are all very large, so compared to the capacitive reactance generated by fingers at the intersection point, other parts of the body can be equivalently insulated.
另外，为详细说明电容耦合触控模式下传感器的位置信息的准确获知，采用笛卡尔坐标系(XY坐标)中坐标点的方式举例说明，可将图4A所示的天线阵列中的各交叉点等效为坐标点，如图4B和图4C所示的X轴和Y轴的坐标点的位置信息说明。以下通过图4A中触控点1的上下移动举例说明每一触控点的位置信息是唯一的。In addition, in order to describe in detail the accurate acquisition of the position information of the sensor in the capacitive coupling touch mode, the way of coordinate points in the Cartesian coordinate system (XY coordinates) is used as an example for illustration. Each intersection point in the antenna array shown in FIG. 4A can be It is equivalent to a coordinate point, and the position information of the X-axis and Y-axis coordinate points shown in FIG. 4B and FIG. 4C is described. The following uses the up and down movement of the touch point 1 in FIG. 4A to illustrate that the position information of each touch point is unique.
具体地，垂直交叉排列第一方向导线组和第二方向导线组，即将第二方向导线组放置于按X轴向，第一方向导线组放置于Y轴向。第二方向导线101a(A5，a5)与第一方向导线201a(B5，b5)的一交叉处有一触控点1，第二方向导线101a(A5，a5)上的交变电压8通过触控点1耦合到第一方向导线201a(B5，b5)输出交变电压9(Ub5)，以及触控点1还与第一方向导线201b(B8，b8)重合，第二方向导线101a(A5，a5)的交变电压8还会耦合到第一方向导线201b(B8，b8)，输出交变电压Ub8。Specifically, the first-direction wire group and the second-direction wire group are vertically cross-arranged, that is, the second-direction wire group is placed on the X-axis, and the first-direction wire group is placed on the Y-axis. There is a touch point 1 at the intersection of the second direction wire 101a (A5, a5) and the first direction wire 201a (B5, b5), and the alternating voltage 8 on the second direction wire 101a (A5, a5) is passed through the touch Point 1 is coupled to the first direction wire 201a (B5, b5) to output an alternating voltage 9 (Ub5 ), and the touch point 1 also coincides with the first direction wire 201b (B8, b8), and the second direction wire 101a (A5 , a5) the alternating voltage 8 is also coupled to the first direction wire 201b (B8, b8), and the alternating voltage Ub8 is output.
若触控点1与第一方向导线201a(B5，b5)的贴合面/重合面大于与第一方向导线201b(B8，b8)的贴合面/重合面，则第二方向导线101a(A5，a5)上的交变电压8通过触控点1耦合到第一方向导线201a(B5，b5)的交变电压Ub5大于耦合到第一方向导线201b(B8，b8)的交变电压Ub8，如图4A1所示，如将触控点1逐步沿Y轴上移，触控点1与第一方向导线201a(B5，b5)的贴合面会逐步减少，与第一方向导线201b(B8，b8)的贴合面会逐步变大，那么第二方向导线101a(A5，a5)上的交变电压8通过触控点1耦合到第一方向导线201a(B5，b5)的交变电压Ub5会逐步减小，耦合到第一方向导线201b(B8，b8)的交变电压Ub8会逐步增大，如图4A2所示，当触控点1沿Y轴上下移动时，第一方向导线组输出的交变电压会有规律的变化，这种电压变化规律是触控点1在Y轴的位置信息，以此可以准确判定出触控点1在Y轴的位置。If the bonding surface/overlapping surface of the touch point 1 and the first direction wire 201a (B5, b5) is larger than the bonding/overlapping surface with the first direction wire 201b (B8, b8), then the second direction wire 101a ( The alternating voltage 8 on A5, a5) is coupled to the first direction wire 201a (B5, b5) through the touch point 1. The alternating voltage Ub5 is greater than the alternating voltage coupled to the first direction wire 201b (B8, b8). Ub8 , as shown in Figure 4A1, if the touch point 1 is gradually moved up along the Y-axis, the bonding surface between the touch point 1 and the first direction wire 201a (B5, b5) will gradually decrease, and the bonding surface between the touch point 1 and the first direction wire 201b will gradually decrease. The bonding surface of (B8, b8) will gradually become larger, then the alternating voltage 8 on the wire 101a (A5, a5) in the second direction is coupled to the alternating voltage 8 on the wire 201a (B5, b5) in the first direction through the touch point 1. The voltage Ub5 will gradually decrease, and the alternating voltage Ub8 coupled to the first direction wire 201b (B8, b8) will gradually increase. As shown in FIG. 4A2, when the touch point 1 moves up and down along the Y axis, the first direction The alternating voltage output by the wire group in one direction will change regularly, and this voltage change rule is the position information of the touch point 1 on the Y axis, so that the position of the touch point 1 on the Y axis can be accurately determined.
同理，可以获取触控点在X轴上的位置，如图4A3和图4A4所示，确定触控点1在X轴的位置信息。由上，可以准确判定出触控点1在X轴、Y轴上的位置即坐标点。根据X轴和Y轴天线阵列上耦合产生的交变电压数据可以准确的计算出触控点1在天线阵列有效区的任意坐标位置，同样原理可以准确的计算出触控点2、3、4在天线阵列有效区的任意坐标位置。Similarly, the position of the touch point on the X-axis can be obtained, as shown in FIG. 4A3 and FIG. 4A4 , to determine the position information of the touch point 1 on the X-axis. From the above, the position of the touch point 1 on the X-axis and the Y-axis, that is, the coordinate point, can be accurately determined. According to the alternating voltage data generated by coupling on the X-axis and Y-axis antenna arrays, any coordinate position of touch point 1 in the effective area of the antenna array can be accurately calculated. The same principle can accurately calculate touch points 2, 3, and 4. Any coordinate position in the active area of the antenna array.
如图4B和图4C解析的触控点1上移的位置坐标点，图4A中的W1W2W3W4为电容耦合感应有效区，Y轴设置Y11-Y0位置，每个位置分别设置天线阵列B4b4、B1b1、B5b5、B2b2、B6b6、B3b3、B7b7、B4b4、B8b8、B5b5、B9b9、B6b6，如分别以字母A、B、C、D、E、F、G、H、I、J、K、L表示第一方向导线B1b1---B9b9，那么Y轴的第一方向导线对应位置的排列表为DAEBFCGDHEIF，排列表每个字母与相邻字母的组合不重复，如A在排列表中的组合有DAE、EAD、DEAB等，在排列表中的其它位置不会有与之一样的组合出现，E在排列表有两个位置，前一位置的组合有EB、AEB、EBF、BFEA等，后一位置的组合有HE、HEI、EIF、IFEH等，在排列表中的其它位置也不会有与之一样的组合出现，Y轴上每个位置的第一方向导线的设置也是以相邻组合不重复为原则排列，X轴和Y轴的每一方向导线的这种不重复排列组合，能保证天线阵列中的交叉点上的触控点精确判定和识别，也可以让具有天线阵列的传感器在电容耦合触控模式下实现多点触控操作。As shown in Fig. 4B and Fig. 4C, the position coordinate point of touch point 1 moved up, W1W2W3W4 in Fig. 4A is the effective area of capacitive coupling induction, the Y axis is set at the position of Y11-Y0, and each position is respectively set with antenna arrays B4b4, B1b1, B5b5, B2b2, B6b6, B3b3, B7b7, B4b4, B8b8, B5b5, B9b9, B6b6, if the letters A, B, C, D, E, F, G, H, I, J, K, L represent the first Direction wire B1b1---B9b9, then the arrangement table of the corresponding position of the first direction wire of the Y axis is DAEBFCGDHEIF, the combination of each letter in the arrangement table and the adjacent letter is not repeated, for example, the combination of A in the arrangement table includes DAE, EAD , DEAB, etc., there will not be the same combination in other positions in the arrangement table. E has two positions in the arrangement table. The combinations in the former position include EB, AEB, EBF, BFEA, etc., and the combination in the latter position There are HE, HEI, EIF, IFEH, etc., and there will not be the same combination in other positions in the arrangement table. The setting of the first direction wire at each position on the Y axis is also based on the principle that adjacent combinations do not repeat Arrangement, this non-repetitive arrangement and combination of wires in each direction of the X-axis and Y-axis can ensure the precise determination and identification of the touch point on the cross point in the antenna array, and can also make the sensor with the antenna array operate in capacitively coupled touch Realize multi-touch operation in control mode.

另外，参照图6所示，图6示出了本发明中传感器实施例中的第二种结构示意图，本实施例中的传感器主要是在上一实施例的基础上增加短路电子开关110或210，以使天线阵列构成的电容耦合触控阵列时，该短路电子开关闭合；由此可以减少天线阵列对交变电压的传输阻抗，提高本实施例中传感器在电容耦合触控模式下的线性度。In addition, referring to Fig. 6, Fig. 6 shows the second structural schematic diagram of the sensor embodiment in the present invention, the sensor in this embodiment mainly increases the short-circuit electronic switch 110 or 210 on the basis of the previous embodiment , so that when the antenna array constitutes a capacitively coupled touch array, the short-circuit electronic switch is closed; thus, the transmission impedance of the antenna array to the alternating voltage can be reduced, and the linearity of the sensor in the capacitively coupled touch mode in this embodiment can be improved. .

其中，如图7A所示，第一方向导线组中的第一方向导线以组合排列方式分布，以及该第一方向导线组中任意相邻的两个第一方向导线间距相等，以及优选设置每一第一方向导线的U形开口部间距相等。图7A中示出的第一方向导线上部电性连接有多个电容耦合触控部件，任意两个第一电容耦合触控部件的形状相同。通常，所述的电容耦合触控部件形状为菱形、矩形、三角形或它们之间任意组合的形状，图7A中仅为实例说明。特别地，可将第一电容耦合触控部件与第一方向导线设为一体。Wherein, as shown in FIG. 7A, the first direction wires in the first direction wire group are distributed in a combined arrangement, and any adjacent two first direction wires in the first direction wire group are equally spaced, and it is preferable to set each The intervals between the U-shaped openings of the wires in the first direction are equal. The upper part of the wire in the first direction shown in FIG. 7A is electrically connected to a plurality of capacitive coupling touch components, and any two first capacitive coupling touch components have the same shape.

The wires in the second direction shown in FIG. 7B are electrically connected with a plurality of capacitive coupling touch components, and any two second capacitive coupling touch components have the same shape. Generally, the shape of the capacitive coupling touch component is rhombus, rectangle, triangle or any combination thereof, and FIG. 7B is only an example for illustration. In particular, the second capacitive coupling touch component and the second direction wire can be integrated.
如图7C所示的实际的传感器结构，其第一方向导线组和第二方向导线组设置为相互垂直交叉，任意相邻的两个第一方向导线和任意相邻的两个第二方向导线的间距均相等，以及第一方向导线与第二方向导线的U形开口部间距相等。特别地，任意两个第一电容耦合触控部件和第二电容耦合触控部件的形状相同。在图7C所示的传感器结构中，在第一方向导线和第二方向导线相互交叉的区域中，所述第一电容耦合触控部件与第二电容耦合触控部件之间的间距相等，以便使任意手指的触控点可包含两个或两个以上的第一电容耦合触控部件和/或第二电容耦合触控部件，进而使得每个方向的导线组中最少两个以上的电容耦合部件包含触控点的交变信息，这种组合能够较好地识别交变信息所对应触控点的位置。In the actual sensor structure shown in Figure 7C, the first direction wire group and the second direction wire group are arranged to cross each other perpendicularly, and any adjacent two first direction wires and any adjacent two second direction wires The distances between the wires in the first direction and the U-shaped openings of the wires in the second direction are equal. In particular, any two first capacitively coupled touch components and the second capacitively coupled touch components have the same shape. In the sensor structure shown in FIG. 7C, in the area where the first direction wire and the second direction wire cross each other, the distance between the first capacitive coupling touch component and the second capacitive coupling touch component is equal, so that The touch point of any finger can include two or more first capacitively coupled touch components and/or second capacitively coupled touch components, so that at least two or more capacitively coupled wire groups in each direction The component contains the alternating information of the touch point, and this combination can better identify the position of the touch point corresponding to the alternating information.
优选地，参照图7D所示，在上述实施例的基础上，第一电容耦合触控部件还可设置为使第一方向导线的等效电磁与第一方向导线方向重叠或者平行的分布；以及第二电容耦合触控部件也可设置为使第二方向导线的等效电磁与第二方向导线方向重叠或者平行的分布。图7D中仅示出了第一方向导线的示意图，在此不限定。Preferably, as shown in FIG. 7D , on the basis of the above-mentioned embodiments, the first capacitive coupling touch component can also be arranged so that the equivalent electromagnetic of the first direction wire overlaps or is parallel to the direction of the first direction wire; and The second capacitive coupling touch component can also be arranged so that the equivalent electromagnetic of the second direction wire overlaps or is distributed parallel to the direction of the second direction wire. FIG. 7D only shows a schematic diagram of the wires in the first direction, which is not limited here.
通常，在实际的传感器结构中，第一导线和第二导线均设置为直线，且第一方向导线上的任一第一电容耦合触控部件在第一方向导线两侧分布的形状对称，或者具有一致的比例关系；以及，第二方向导线上的任一第二电容耦合触控部件在第二方向导线两侧分布的形状对称(即沿第一导线/第二导线的上下对称)，或者具有一致的比例关系，以便该实施例中第一方向导线的等效电磁和与第一方向导线方向重叠或者平行的分布，第二方向导线的等效电磁和与第二方向导线方向重叠或者平行的分布。该传感器中的天线阵列能够使第一方向导线组和第二方向导线组输出的信号与上述图7C中示出的天线阵列输出的信号等效一致，以便可准确获知电磁感应触控模式或电容耦合触控模式下的触控点的位置信息，且使连接天线阵列的外部控制部件的内部运算简单。举例来说，可能存在第一电容耦合触控部件在第一方向导线两侧分布的形状不对称，但获取的等效电磁不在一条直线上，其易导致外部控制部件识别的信号杂乱，进而使外部控制部件计算的复杂性提高，以及可能存在无法准确定位触控点的具体位置，故在本实施例中优选将第一导线和第二导线均设置为直线，以使第一方向导线和第二方向导线各自的第一导线和第二导线上的等效电磁在一直线上。Usually, in an actual sensor structure, both the first wire and the second wire are arranged as a straight line, and any first capacitively coupled touch components on the first direction wire are symmetrically distributed on both sides of the first direction wire, or have a consistent proportional relationship; and, any second capacitively coupled touch components on the second direction wire are symmetrical in shape distributed on both sides of the second direction wire (that is, vertically symmetrical along the first wire/second wire), or Have a consistent proportional relationship, so that in this embodiment, the equivalent electromagnetic sum of the first direction wire overlaps or is parallel to the direction of the first direction wire, and the equivalent electromagnetic sum of the second direction wire overlaps or is parallel to the direction of the second direction wire Distribution. The antenna array in the sensor can make the signals output by the first direction wire group and the second direction wire group equivalently consistent with the signals output by the antenna array shown in FIG. 7C above, so that the electromagnetic induction touch mode or capacitance can be accurately known. The position information of the touch point in the touch mode is coupled, and the internal operation of the external control part connected to the antenna array is simplified. For example, there may be an asymmetry in the shape of the first capacitive coupling touch component distributed on both sides of the wire in the first direction, but the obtained equivalent electromagnetic is not on a straight line, which will easily lead to confusion in the signal recognized by the external control component, and then make the The complexity of the calculation of the external control components is increased, and the specific position of the touch point may not be accurately located, so in this embodiment, it is preferable to set the first wire and the second wire as a straight line, so that the first direction wire and the second wire The equivalent electromagnetics on the first wire and the second wire of the wires in the two directions are on a straight line.
